Introduction
The LU is a lightweight unit that enables anyone to transmit live video or data
at the tap of a button using multiple existing cellular or wirele ss
infrastru ctures, as well as directly via the Ethernet (LAN).
It is designed to transmit high-quality live streaming video from the field for
any type of event, such as breaking new s, spo r ts or live interviews, without
the need for costly satellite or microwave uplink units.
NOTE
network reception and provides additional resiliency for live video
transmission in extreme scenarios, such as heavily crowded locations.
You can use this device to incre ase network reception of the LiveU
LU60/LU70 units to which it is connected.
Contact LiveU for more details abo u t pur chasing this option. The LiveU
Xtender is described in the LiveU Xtender User Gui de.

LiveU Live Video Uplink System User Guide
System Overview
The LU Live Video Uplink unit simultaneously aggregates a numb er of
networking infrastructure s ( cellular, Wi-Fi and so on) in order to stream live
audio and video from field locations to the LU-1000 central server, which is
usually located in a broadcasting center.
The LU-1000 server gathers the live video feed via a secure Internet
connection and is then able to supply this feed to the production suite, routing
table, website and such for furthe r pr o ce ssing.
The technology offers a viable alternative to traditional uplinks, both in terms
of video quality, as well as in pricing, immediacy of service, av ailability and
portability.
An example of a typical deployment of the LU (client) and LU-1000 (server) is
shown below:
Figure 1: Solution Architecture
14
Page 15
Wireless Connectivity
The LU unit is designed to search for and connect to whichever cellular,
wireless or Ethernet (LAN) data infrastructures are available. The system has
several bui lt -in interfaces that are able to estab lish a connection to many
different networks simultaneously in order to over com e inherent bandwidth
limitations and offer robust transmissions. In addition, for areas where cellular
transmissions are problemati c, it is possible to use other available wired or
wireless Internet connections.
When the operator begin s u sing the LU unit by tapping Connect, the system
automatically searches for and conn ects to all the interfaces it detects in the
immediate area and then automatically analyzes and calibrates the system to
provide the best possible broadcast according to the Profile selecte d by the
camera operato r and the actual air bandwidth.
The LU system’s flexibility enables users to select different conf igurations for
certain situations where it may be necessary to manually reconfigure the
original setup. For example, when the required bandwidth for transmission
may not be sufficient or the video resolution may need to be change d from
broadcast to broadcast.
Overview
When broadcasting over cellular or wireless infrastructures, the physical
location of the LU unit should be taken into consideration. The LU contains a
proprietary set of interna l a ntennas, which enables operation even in typical
Dead Cellular Zones. Even so, there may still be areas where the netw o r k
reception is poor and the unit must be moved in order to receive a better
signal. For exampl e, when broadcasting from a n indoor locatio n, it may be
necessary to move the unit closer to a window to get better reception.
NOTE
The LU live video uplink operates on wireless netwo r k s. You should
therefore refer to Appendix D, Safety and Maintenance on page 139
for safety instructions and fo r a description of other regulations
regarding the operation of the LU sy stem.
15
Page 16
LiveU Live Video Uplink System User Guide
LU as an Access Point
The LU can serve as an access point for enabling wireless device(s) in its
vicinity. For example, it can ena bl e the laptops near it in the field to connect
wirelessly to the Internet thr o ugh its cellular modems.
LU Device Types
LiveU provides the LU60/LU70 family of products for professional broadcast
applications. These products have a proprietary internal antenna arr ay that
extends cellular range, extends cellular dead zones into live zones and
provides a cost effective integrate d r o aming support option. The LU60/LU70
family supports up to 1080 full HD video.
The LU60/LU70 devices may be provided with one of the following video input
options:
• SDI Video + DV, or
• HDMI + Analog Composite + DV

A full description of the user interfa ce is provided in Chapter 3, L U User
Interface on page 33.
Step 2, Connec tin g the Video Camera
The procedure for connecting a video camera to a LU live video uplink unit is
simple.
Only one camera can be connected dire ctly to the LU unit at any one time. It is
possible to connect devices that act as a hub for cameras using FireWire to the
LU unit. Such devices are sometime s called Quad. However, even if more than
one camera is connected in this manner, only one feed from one camera at a
time is recognized and transmitted.
The following describes the procedur e f o r connecting a camera to the
LU60/LU70.
23

LiveU Live Video Uplink System User Guide
For an HDMI camera, HDMI cable BIDs are required in order
LU60/LU70 – Connecting the Camera
Different models of the LU60/LU70 are provided, each with the ability to
connect to different cameras. All models connect to DV (FireWire 1394)
cameras. The following LU60/LU70 unit connection options are available:
SDI + DV (FireWire 1394)
Figure 6: LU60/LU70 with SDI Camera Connection
For an SDI camera, only use the middle SDI co nnector.
• HDMI + Analog (Component, Composite and S-Video) + DV (FireWi re
1394)
Figure 7: LU60/LU70 with DV, HDMI and Analog Camera Connection
For an HDMI camera, only use the HDMI IN connector.
IMPORTANT
to ensure compatibility with FCC standards. If your kit does
not include these, then you may request them from LiveU.
They will then be provided free of char ge .

Getting Started
NOTE FOR DV
► To connect the camera:
1 For DV cameras, it is recommended to f irst power up the LU, and only then
to connect the camera to the LU.
An SDI, HDMI or Analog camera can be connected either before or after
turning on the LU.
2 For a DV (FireWire) camera, check that the camera is turned off and NOT
connected to any external power supply. SDI, HDMI or Analog cameras can
be powered on either before or after being connected to the LU.
3 Appropriate cables are provided for each type of c amera. Conne ct one end
of the appropriate camera’s cable to the relevant port on the video
camera.
IMPORTANT
In order to avoid permanen t d amage to a Fire Wire/DV
camera and the LU Live video uplink unit, you must only
(FIREWIRE)
use the LiveU provided FireWire/DV (1394E) cables!
CAMERAS
LiveU provides two types of FireWire/DV (1394E) cables:
one type connects 4 pins to 6 pins, wher e th e power is
connected, and the other type conne cts 6 pins to 6 pins.
4 Connect the other end of the cable to the appropriate port (DV IN, SDI IN,
HDMI IN or A/V Analog) on the LU Video Uplink unit, according to the type
of camera, as follows:
For a DV camera, connect to the DV IN connector.
For an SDI camera, connect to the middle SDI connector .
For an HDM I camera, connect to the HDMI IN connector.

5 For DV cameras, after the camera is attache d to the unit, you can connect
an external power supply to the camer a, if ne eded. Then, turn the camera
on.
6 The camera video is automatically displayed on the unit’s screen, if the
camera is on and properly configured. The screen on the unit’s interface
should display the scene that the camer a is capturing.
Step 3, Connecting to the LU-1000
In order to stream video using the LU Live Video Uplink system, it is necessary
to connect the unit via the Internet to the LU-1000 server usin g o n e o r more
wireless networks. The LU-1000 server is usually located at the br o adcasting
center.
► To connect to the LU-1000:
• Tap the Connect button .
The Connect button on the display changes to ReConnect.
NOTE
The LU unit automatically searches for and detects the interfaces (ce llular
modems, Wi-Fi, LAN and so on) that are available on the unit and connects
to each one.
As each interface is connected the fo llowing is displayed for each:
Figure 9: Connecting to an Interface
This process may take up to five minu tes to co mplete.

The Connecting status indicator is displayed, as shown below:
Figure 10: Connecting Status Indicator
Even though the LU can operate withou t all interfaces, it retries connecting
a number of times before giving up and displaying the following message:
Figure 11: Interface Connection Failed
After the modems are connected, the system carries out network -related
tests and the application automatically calibrates the available b andwidth
efficiency and delay for each of the inte r faces. It also determines the best
parameters for ensuring that the system fu n ctions at maximum efficiency.
After this calibration, the LU application is able to calculate the ov erall
system efficiency, total effe ctive bitrate and delay.
After the system has finished this cal ibration, the LU unit automat ically
sets the video bitrate to the value reco m mended by the system according
to combination of selected Profile and Resolution.
NOTE
If the connection process results in a low v ideo rate, tap
ReConnect. The system then recalibrates itself. If the problem
continues, then you can change the video bit rate manually using
the Options button Configuration button Media button, as

Transmission
This chapter describes some of the aspects on which successful transmission
of a high-qua lity audio/video stream depend, such as video resolution, targ et
resolution, bitrate, CODEC and so on.
This chapter contains the following sections:
• Overview, page 47
• Profiles Window, page 48
• Changing the Profile, page 50
Overview
• Changing a Profile’s Resolution, page 55
Successful transmission of a high-quality audio/vide o stream depends on a
number of elements, such as video resolution, target resolution, bitr ate,
CODEC and so on. The LU unit analyzes the cur r ent network conditions and
sets the optimum configuration auto matically. However, if conditions warrant,
it is possible to adjust several of thes e elements manually.
Target Audience
The target audience should be decided before starting transmission. In other
words, the camera operator should know what is being filmed and how it will
be broadcast from the studio. With this in mind, it is possible to select the
appropriate parameters to ensure the best broadcast.
47
Page 48
LiveU Live Video Uplink System User Guide
The main factors when deciding target resolution are the quality of the
broadcast and the delay. For example, if the event is a sporting event
(Olympics, a ball game and so on), then it is important to use the highest
bitrate available. If the b roadcast is an interview aft e r the game, the n a lower
bitrate is effective. If the broadc ast is for the Internet, it is not always
necessary to use a resolution greater than CIF or half D1.

Interview Profile Delay
Interview profile allows for the shortest delay, 1.35 – 5 seconds. The delay in
this Profile is automatically set by the system after calibration and depends on
the selected resolution. The R ec om m end ed del ay checkbox is automatically
selected to indicate that this Profile is using the automatically delay set by the
system after calibration.
You can manually set the delay and overr ide the system’s automatic
recommendation by checking the Custom delay checkbox. The system then
displays the upper and lower permitted delay limits according to the
performance of the Interfaces measured in the Calibration process during the
Connect phase. You can then type in or use the slider to specify the des ired
delay. Please note that reducing the delay below the syste m ’s r e commended
one may result in less video resiliency and/or image qua lity.
Generally, as a rule of thumb, the longer the delay, the better the
system reacts to temporary air b andwidth deterioration.
NOTE
In Guaranteed Only mode, the minimum Custom Delay is 1.4
seconds. In Use All mode, the minimum Custom Delay is 1.6
seconds. For more details, see page 76.

Balanced Profile
Select the Balanced Profile when the delay starts to become important, yet
an Interview delay is not mandatory. This setting provides high image quality
with medium end-to-end delay. This Profile does not have a configurable
custom delay.
Figure 33: Balanced Profile
The Balanced Profile normally uses fewer modems by eliminating those with
relatively high delay in order to reduce transmission latency. As it optimizes
the system for a relatively short delay, 5 – 12 seconds, it is subject to
interference in unstable networks (where there is an interrupted signal or
change in bandwidth). For example, when you are broadcast in g from a moving
vehicle that enters a tunnel and the signal is interrupted for a minute or two .
When using this setting there is on ly a slight room for recovery, and as a
result the broadcast may be affected.

Max Quality Profile
This Profile is selected by default.
Select the Max Quality Profile when the quality is of prime importance and
the delay is not important.

This Profile provi des th e best image quality at a potentially higher end-to-end
delay. The system is optimized for m aximum stability with more emphasis on
the integrity and quality of the transmitted video. It tells the system to use all
the available connection s in order to gain the maximum bandwidth poss ible
and configures the system to deliver the best resolution.
Max Quality Profile Delay
Max Quality profile allows for the longest delay, 12 – 60 seconds to

Generally, as a rule of thumb, the longer the delay, the better the
system reacts to temporary air bandwidth deterioration.
Changing a Profile’s Resolution
The video Resolution determines the horizontal and vertical size of the video

The same resolution optio ns are provided for all Profiles. The default option is
Automatic, whic h specif ies that the optimal resol ution for each Profile is
automatically selecte d. Typically, there is no need to change it.
An example of when you may want to change a Profile is when 3G signal
quality is fluctuating because of the en vironment or because of your lo cation.
This could happen while driving, riding the subway or while switching between
indoor, outdoor and underground locations during filming. In this case, you
may want to set the lowest resolution: CIF or ¼ HD. This resolution ensure s
proper quality under fluctuating 3G signal conditions, but does not increase
resolution when signal quality improves (as Automatic does).

is approximately 512 Kbps. The optimal bitra te for Half-D1 is between
750 Kbps and 1.5 Mbps.
• VGA: NTSC Only | PAL 640x480: This provides ne a r Full-D1 qu al ity ,
which is used by some websites. Use th is resolution when a higher quality
is needed and enough bitrate is ava ilable. The lowest bitrate that sho u ld be
considered in this case is about 7 50 Kbps. The optimal bitrate for VGA is
between 1 Mbps and 2 Mbps.
• D1: NTSC 720x480 | PAL 720x576: This is the highest SD resolution
currently supported by the LU live video uplink, and is normally used for
SD live TV broadcasts when the highest q uality picture is required. Only
consider transmitting Full-D1 when the overal l available bitrate is over
1 Mbps. The optimal video bitrate for Full-D1 transmission is between 1.5

File Transfer
This chapter describes how to use the LU to transfer files from the field directly
to the LU-1000 server.
Transferring Files
The LU Live Video Uplink System enables you to transfer prerecorded files to
the LU-1000 server so that they may be saved f o r future use. This feature can
also be used to transfer any other type of file, such as text files, documents
and so on. Files can even be transferred while the unit is broadcasting
(playing).
Files can be transferred from the LU unit itself or f r o m a USB device, such as a
camera with USB interface attached, which can be attached to the LU unit.
One or more files can be selected to be tr ansf erred.
The files are stored on the LU-1000 server in the directory designated for this

Media
The Media tab, shown above, enables you to manually define the
encoding-related parameters used to configure audio and video, as follows.
NOTE
CODEC
Select H.264 (default) or External CODEC, as described below. T h e
configuration parameters displ aye d in this window change according to the
CODEC that is selected.
H.264
The H.264 CODEC is the default option, which supports all Resolut ions. It is
shown above in Figure 73.
The Advanced button pro vides additional media settings, calibration
network interface connec tions, license and utilities options. These
options are only for technicians; they are password-protected and are
not described in this manual.
The H.264 CODEC is an improved video encoder. It allows near realtime
encoding and supports an adaptive bitrate, which increases resiliency.
If the bitrate drops, then the video stream does not flicker or freeze. It also
allows encoding in near re a l time, enabling up to Full D1 video images in both
NTSC and PAL at full frame rate.
• Limit Video Rate: The video rate is set automatic al ly by th e application
following calibr a tion. Yo u can override the video bitrate by selecting the
Limit video rate checkbox and then setting it m anually after calibration
has taken place. The recommended video rate range is displayed under the
field along with the curren tly selected Prof ile and Resolution. The
recommended range varies according to the selected Profile and
Resolution.
• Support 4:2:2: Spec ifies that the LU supports encoding video with 4:2:2
color profile.

• De-interlace: Tap to mark/unmark the De-inter lace option. This option
performs preprocessing on the input interlaced video stream and converts
it to non-interlaced (progressive).
NOTE
De-interlac e is only available in D1 (Full) and i n VGA resolution.
This optio n is disabled in bo th CIF and Half-D1 resolutions
because the video stream in these resolutions is already
non-interlaced, because the resiz ing mechanism accomplishes this
process.
• Automatic FPS Reduction: Specifies that the LU monitors network
conditions and dynamically reduce s the transmitted video’s frame s per
seconds, if needed, in order to provide more stable video output. This
means that the LU automatically ad justs itself to conditions in the field and
changes the FPS according to the qu al ity o f the connection in order to
ensure a constant rate of transmission.
For example, when network conditions are poor, the FPS is reduced. The
FPS automatically returns to its previous setting when network conditions
improve.
Audio Ra t e
The audio is compressed using AAC CODEC. The default and recommended
audio bitrate is 64 Kbps.
